INVENTOR- UNrrEn srarss wr THOMAS A. HOOVER, OF FRESNO, .CALIEORNIA man .ersten VEHICLE-SPRING.

To (171 Aw/zm/z, 'if may (fon/erm VBe it known 'that fl, "ill-'nomas A. Hoeven, a citizen of the United *State-s, residing atlivresno, in the county of fFresno and -State 'of California, have in veixted certain new Figure 1 is a plan and Fig. Q is an elevation of a semi-elliptical spring embodying this invention; Fig. 3 is a fragmentary section showing the manner in which the leaves of the spring are held together; Fig. 4 is a plan and Fig. 5 is a central vertical section through the clip-plate; Fig. (5 is a fragmentary detail showing a portion of a leaf of the spring; Fig. 7 is a detail showing the spring lock-plate; and Fig. 8 is a detail hereinafter referred to.

Each of the leaves b of the semi-elliptical spring o is formed with a central hole Z1 through -which is passed the shank of the bolt c. Upon the latter is then screwed the nut d, whereby the leaves Z) of the spring are tightly drawn together. Over the projecting upper end of the holt -c there is now passed a clip-,plate e formed with a square central hole e and with :tour bolt holes c for the clip-bolts f. -Thegnut dgits snugly within the squarehole e of the clip-plate e,

.which therefore serves to prevent the rotation of the nut d. The spring a rests upon the usual spring-block g in which is mounted the axle end h and .the top face of which is forined with a central: countersink or socket gx adapted to receive the head C of thc holt c. 'lhe spring-block g,is furthermore fernied with holes g at its corners through which pass the bolts f and with countersinls g" in its lower face in which are iitted the heads of the bolts f.. These countersinks prevent the latter from turning; and upon the upper ends of the saine i. Specification of Letters .Patent 'Patented July 1 5, i913.

are screwed `the-.nuts Arranged fentrally between the latter is a spring torti-plate j forniedwvith a centralhole j through which .projects the-threaded upperend of the lholt c, .upon which is screwed the nut L'. .lhe upper faceof the Aelipplate c is slightlir Ydished (this dish is yexaggerated for pur' poses of illustration in Fig. and, when the -nut 7c isscrewed down :upon the spring `luik-plate, the' resiliency of the latter causes a 'pressure to be exerted upon the nut vr. which is lthen held in place by the friction existing between the spring lock-plate and the nut. It is to be observed further that. the spring lock-plate .Serves to prevent the turning of the nuts a' on the upper ends of the bolts f.

Freni the foregoing arrangement of parts, it will be seen that the parts of the spring are firmly secured together and interloclied, whereby looseness and rattling of these parts are obviated.
